1. A yaw-rate forecasting system for a vehicle, the system comprising:
- a yaw rate sensor configured to detect a yaw rate of the vehicle and generate a signal indicative of the detected yaw rate;
an electronic control unit coupled to the yaw rate sensor, the electronic control unit configured to receive the signal indicative of the yaw rate of the vehicle from the yaw rate sensor, generate a model of a future yaw rate using the detected yaw rates, verify an adequacy of the model, extend the model if the model is found to be inadequate, forecast a future yaw rate based on the model, or extended model if the model is found to be inadequate, determine a stability of the vehicle using the forecasted yaw rate, determine, an action to take based at least in part on the predicted yaw rate, and generate a signal to control actuation of a vehicle brake;
wherein the model is determined to be adequate when a significant reduction in a residual sum of squares is no longer seen with a higher order model.

Abstract
A yaw-rate forecasting system for a vehicle. The system includes a yaw rate sensor and an electronic control unit. The yaw rate sensor is configured to detect a yaw rate of the vehicle and to generate a signal indicative of the detected yaw rate. The electronic control unit is coupled to the yaw rate sensor, and is configured to receive the signal indicative of the yaw rate of the vehicle from the yaw rate sensor, forecast a future yaw rate, determine a stability of the vehicle using the forecasted yaw rate, and to generate a signal to control actuation of a vehicle brake.

13. A method of stabilizing a vehicle based on a predicted future yaw rate of a vehicle, the method comprising:
-
detecting a plurality of yaw rates of the vehicle over a period of time by a yaw rate sensor; providing an indication of the detected yaw rates to a controller; the controller; generating a model of a future yaw rate using the detected yaw rates; verifying an adequacy of the model; extending the model if the model is found to be inadequate; determining a predicted yaw rate for a moment in the future based on the model, or the extended model if the model was found to be inadequate; providing the predicted yaw rate to an electronic stability control system; and determining, by the electronic stability control system, an action to take based at least in part on the predicted yaw rate, and generating a signal to control actuation of a vehicle brake; wherein the model is determined to be adequate when a significant reduction in a residual sum of squares is no longer seen with a higher order model. - View Dependent Claims (14, 15, 16, 17)
